GASKET.

Application filed November 23, 1921.

To ZZ yifi/om t may concern.'

Be it known that CLYDn C. FARMER, a citizen ot' the United States, residing at Pittsburgh, in the county of Allegheny and State ot Pennsylvania., have invented new and useful linprovements in Gaskets, olf which the following is a specilication.

This invention relates ato a gasket adapted to be applied to the tace of a contact carn rier of an electric train line coupler such as employed for connecting electric train lines between cars of a train.

The principal object of my invention is to provide an improved gasket of the above cliaracter which will effectively protect the contacts against the weather.

In the accompanying drawing; Fig. l is a. sectional view oi' portions of counterpart electric train line couplers in the coupled position, and showing my improved gasket applied thereto; Fig. 2 a plan or face view ot' the gasket; and F ig. 3 a section of the gasket on the line 3 3 of lig. 2.

As shown in Fig. l, the electric coupler may comprise a metallic casing l, substantially rectangular in cross-section, and containing a block 2 oi' insulating material, within which are mounted a plurality of electric contacts 3. The projecting :tace end o'l the block 2 is provided with a groove e which continues around the four sides of the block and is adapted to receive the head 5 of a flexible rubber gasket 6. The gasket is provided with a relatively thin outwardly flaring` portion 7 forming an exterior groove or cutter 8.

ln the act of coupling electric train line couplers provided with the improved gasket, the flared portion 7 ot' the gasket on one coupler head engages the corresponding portion ot the gasket on the counterpart Serial N0. 517,199.

coupler head, both flaring portions curling up as the contacts 3 approach engagement, until in the coupled position, the portions 'T of the gaskets assume the shape as shown in Fig. 1.

By means ot the above described construction a high degree of leXibility is secured, so that the gaskets offer little resistance as the couplers are brought to the coupled position. This is an important it'eature, since it is highly desirable that the force required to brine' the couplers to the coupled position be reduced to a minimum.

Any water, due to weather conditions, which may collect in the V-shaped trough formed by the abutting gaskets will be forced out into the gutters 8, when the couplers are uncoupled, by the rolling action oi? the flexible portion T on each other. It will also be noted that contact between the gaskets will be maintained during the uncoupling movement until the electric contacts are fully separated.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is

A coupler gasket for engagement with a counterpart gasket having a thin flexible arcuate portion with a iree edge normally Jfacing radially outward, the liexible portion curling rearwardly upon engagement with a counterpart gasket and the lree edge moving forward to meet the tree edge ot the counterpart gasket at the instant oli separation of the gaskets, whereby moisture collecting between the gaskets is expelled upon separation of the gaskets.

In testimony whereoil l have hereunto set my hand.
